“Gravity Batteries”
Below is a claim about a type of energy storage that exists in great abundance today in the form of pumped hydro. We take off-peak electrical energy and use it to lift a mass against the force of gravity, converting …
“New” Concept in Energy Storage
Here’s a piece on a subject we haven’t talked too much about recently: energy storage. In this case, it’s analogous to pumped hydro (see left) or advanced rail energy storage, both of which take off-peak energy and use it to …
Jigar Shah, Clean Energy Icon
Here’s a story about Jigar Shah, long-term friend and colleague, and how he finds himself in a position within the U.S. Department of Energy to make loans totaling hundreds of billions of dollars to companies in cleantech. As the director …
Green Infrastructure
A companion point to be made here is that, in the absence of green infrastructure, the United States is actively contributing to the incineration of our planet. In addition, building low-carbon energy generation, electric transportation, smart grid, energy storage, and …
CleanTech: Nothing Succeeds Like Success
This fellow asks a very good question. When indeed? First, let’s realize that America is the only nation that has trouble assimilating this idea. We are also a culture that worships money, and in this case, that may turn out …
Renewables Without Subsidies

Elon Musk’s Bet on Building-integrated Solar PV
Building-integrated solar PV (BIPV) isn’t new, so what’s all the fuss about Elon Musk’s venture into the industry? Answer: Elon Musk. A name not to be trifled with. Analysts say he won’t be able to meet his target (1000 solar …
Why Has Wave Power Been Slow to Take Off?
Here are excerpts from the article linked below that attempts to answer the question posed above. After each, I’ll add my own comments. Article: Why has wave power lagged behind other renewable energy sources?
